From developer to architect–A logical evolution…or not?

Most of the people I have the pleasure to work with are developers, all great, intelligent people with passion for technology and IT. When I talk with them about their career and how they think they should evolve, a lot of them aspire to become an architect. Now the job title architect can mean a lot of different things, but that is not the topic I want to rant about today Smile

*** START RANT ***

I’m a little bit puzzled why a lot of developers think that becoming an architect is the logical way forward. Why you ask me? Let me explain…

Developers are creative people, great thinkers and problem solvers. They like to tackle complex problems, that’s what they live for. Once they are no more problems to solve, they start to get bored and start looking at new frameworks and tools just to have new problems to tackle. Developers LOVE complexity.

“Developers are attracted to complexity like moths to a flame”

As an architect it is quite the opposite. You are not aiming for sprints but want to do marathons. Every decision you take has an impact that can haunt you forever(until the next rewrite arrives Winking smile). Therefore as an architect you should be risk averse, better safe than sorry. Architects HATE complexity. It makes every solution unmaintainable in the long run. Simpler IS better…

As an architect you strive for a clean architecture with only an essential level of complexity and try to avoid accidental complexity at all cost. Developers are proud on the clever solutions they create(and they should be!) but as an architect simplicity will always win over cleverness in the long run.

This made me wonder if becoming an architect is such a logical stepping stone in the career of a developer. It’s a complete mindswitch which is not easy to take(ask me…).

Food for thought… (Now I have to go, I have to create a Functional Reactive DDD CQRS Microservice DevOps architecture to get some data out of the database and show it on a website Punk)

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cache stampede: when our cache turned against us

While investigating some performance issues, we ran into an ASP.NET Core API that cached a fairly expensive aggregation query for 60 seconds. Under normal load, that was fine: one request rebuilds the cache, everyone else reads from it. Under peak load, dozens of requests would arrive in that same expiry window, all see a cache miss, and all fire the same expensive query in parallel. The database didn't like that. That was the moment when our caching layer stopped helping and started hurting. A burst of requests comes in at the same time, all miss the cache, and all go hammer the database or the downstream API at once. That's a cache stampede . The cache was supposed to protect our backend, and for a few hundred milliseconds it did the opposite. Why this happens IMemoryCache.GetOrCreate (and its async sibling) looks like it protects you, but it doesn't add any locking on its own. Look at the naive version: public async Task<Report> GetReportAsync(string key) ...
